. EMERGENCY LOCKING MECHANISM.

To all whom it may concern; 1

Be it known that I, WILLIAM CHARLES PARKER, a subject of the King of Great Britain, and a resident of Chicago, in the county of Cook, State of Illinois, have inventedcertain new and useful Improvements V in Emergency Locking Mechanism, of which l remote point or, pointssuch as a bank tell ers cage, and in a'positive and substantial manner, all as willhereinafter more fully appear.

In the accompanying .drawing: W V Figure 1, is a-v plan, view .of the revoluble member of the present mechanism.

member, and 5 the fixed member of the present emergency locking'mechanism.

The guide late 1 aforesaid, is secured to a carrying bracket or post 6 of the fixed member 5 and'is provided with a guide slot f 7 to receive and guide the free end of the operating bar 2, and the saidguide slot is preferably inclined as shown, sothat the Specification of Letters Patent.

tendency of the operating bar 2 will be toward an inoperative position under the ordinary jarring of the building.

The latch bar 2 aforesaid, is pivoted to a lateral post 8 on the fixed member 5, with its free end in guiding engagement with the slot 7 of the guide plate 1 aforesaid, said bar 2 is provided with one or more holes or orifices 9 for the attachment of pull wires which extend to remote points in the building so that the bar 2 may beactuated by persons at such remote point or points. The scope of the present invention however, embraces an actuation of the operating bar 2 from a remote point by any usual and suitable intermediate mechanisnis.

The latch bolt 3 aforesaid is of a cylindriper portion 10 adapted to rest upon and be supported by the guide plate 1 in a normal inoperative osition.

cal form and provided with an angular up- 7 .larly formed hub 14 of the fixed member 5 hereinafter described. In the portion of said member 4 intermediate of the flanges 12 and 13 above described, is formed a circular seriesof vertical holes or orifices 15,. adapted for'locking engagement. with the lower end of the latch bolt 3 aforesaid.

. The fixed or stationary member 5 aforesaid, is of a flat plate form and provided with screw holes adapting the same for fixed attachment to the stationary housing of a revolving door in a strong and substantial manner; On its lower surface the member 5 is formed with the cylindrical hub 14: afore saidand which byits engagement in the cylindrical socket of the revoluble member 4 is adapted to maintain the parts in rotative engagement in actual use. On its upper surface the member 5 is provided with a lateral post 8 and with the bracket or post 6 above described, and with a vertical guide hole or orifice 16 arranged in axial a1ineventi'onwhat I claim as new ment with the'bolt'holes '15 'ofthe revoluble member 4: and adapted to receive and guide the latch bolt 3 in actual use, I

In the operation of the present invention,

as the operating bar 2 receives vpivotal movement from a remote point as above set forth, it moves away from the latch bolt Sand luble member 43 to lock the same from any further rotation, and thus attain a locking of the revolving door of the building until the latchbo'lt 3 is removed from'thelocking engagement just described. The unlatching and resetting of the latch bolt'8 to the normal inoperative condition first described, is

effect-ed by hand through a suitably guarded passageway in the stationary housing of the revolving door, and arranged in any safe and convenient manner which the judgment of the constructor may deem best.

, Having thus full described my said in-;

and desire to secure by Letters Patent, is z 1. An emergency locking means for revolving doors, comprising a fixed member adapted for attachment to a door housing and having a support and guide for alatch bolt, a latch bolt associated with saidsupport and guide, a revoluble member adapted for attachment to a revolving door and formed with a circular series of bolt holes adapted for engagement with the latch bolt 7 aforesaid, and means adapted foroperation from a remote point for 'releasingthe latch 7' bolt for a locking engagement, substantially as set forth.
